Percy could also be a bit critical. Since he's so familiar with his own world of Greek mythology, he might notice inaccuracies in how the fanfiction blends Norse elements. For example, if the fanfiction misinterprets how magic works in the Magnus Chase world compared to what he knows from his own experiences. He might think, 'Well, that's not how things should be in a world of gods and heroes, even if it's Norse and not Greek.'
He might be amused. Percy has his own set of adventures, but reading about Magnus' would probably make him chuckle at the different takes on Norse mythology in the fanfiction.
On the other hand, Percy might get some new ideas for his own adventures. The fanfiction could introduce him to unique concepts from the Magnus Chase series. Maybe there's a cool weapon or a strange creature in the fanfiction that he could imagine using or fighting in his own world. He could be inspired to tell Annabeth about it and they could discuss how such things could be adapted to their own quests.
If Percy reads positive fanfiction about Magnus, he might develop a new - found respect for him. He could start to think of Magnus as more of an equal in the world of demigods, even though they are from different mythologies. For instance, if the fanfiction shows Magnus doing heroic deeds, Percy would recognize the similarities between their roles as heroes. However, if the fanfiction portrays Magnus in a negative way, Percy might be a bit more cautious around him, wondering if there's some truth to those made - up aspects.
Percy could find it both strange and fascinating. Since he has his own set of adventures and challenges, reading about Harry Potter's world through fanfiction might make him think about how different yet similar their situations are. He might be amused by some of the out - of - the - box ideas in the fanfiction.
You can start by looking on fanfiction websites like Archive of Our Own (AO3). There are tons of great Magnus Chase and Percy Jackson fanfics there. Just use the search function and type in the relevant tags.
The Titans from Greek mythology could also be a good choice. Imagine if the Titans, who are still bitter about their defeat by the Olympians, team up with some of the more malevolent Norse giants. They could try to take over both the Greek and Norse realms, forcing Percy and Magnus to join forces to stop them.
He might find it really interesting. Since both Percy Jackson and Carter Kane are from different but equally rich myth - based series, he could gain new perspectives on how to blend modern settings with ancient myths, which is something his own series also does.
Percy's water - based powers and Magnus's ability to communicate with the dead could create some really interesting scenarios. For instance, Percy could use water to expose hidden passages in cemeteries where Magnus could then communicate with the spirits to get information.
I really like the idea of Percy and Magnus just chatting about their lives. Percy talking about his experiences with the Greek gods and Magnus sharing his Norse - related adventures. It would be a simple but really engaging interaction.
Time - travel is another trope that shows up. Writers might send Percy or Magnus back in time to change something in the other's world. It creates a lot of opportunities for adventure and exploring different time periods in the Riordanverse. This can also lead to some really cool crossovers between the mythology of the two series.
Well, it could be really interesting. Percy could introduce Magnus to the Greek gods and their ways, while Magnus shows Percy some of the unique Norse magic. They could go on an adventure together, perhaps to retrieve a powerful artifact that has significance in both mythologies. Their different skills and personalities would make for a great dynamic. Percy's swordsmanship and water - based powers combined with Magnus's ability to talk to the dead and his knowledge of Norse runes could lead to some really cool battle scenes and problem - solving situations.
One interesting crossover could be a quest where Magnus and Percy have to team up. They could combine their different powers, like Percy's water - based abilities and Magnus's connection to Norse mythology. For example, they might face a sea monster that has a connection to both Greek and Norse realms. Another could be a story where they end up in each other's worlds and have to adapt. Percy in the Norse world would be really fun to read as he tries to figure out the different rules and gods there, and vice versa for Magnus in the Greek world.
